Any replies? I really appreciate any information asap.... I need to take a decision pretty soon.

HELP PLEASE!

Hi Michael,

Make sure they are SKF or Timken. They both work fine.

Thank you Paolo. Do you recommend any specific model&type of these brands?

Michael, we have disc cutter workshop in one of our sites. Let me check with them I'll be back on this.

ORS (https://www.ors.com.tr/) produces very reliable and long-performance ball bearings for the disc cutters. You must try a few to get really see the great performance level.

Still awaiting specific model&types for bearings...
Anyone?

Hi Mike,

I know this thread is almost a year old but better late than never, I answer anyway.

Your best bet is Timken ball bearings. Specifically you need this for a 17" Disc cutter:

Part Number HH224332 - HH224310-B, Tapered Roller Bearings - TSF (Tapered Single with Flange) Imperial

All technical info you need is at the manufacturers' site (link below)

Hope this info needs somebody even if late for you man.

stay tight,

It is also my personal experience that Timken bearings perform better in disc cutters. In medium hard rock we bored once 1.1 miles without any bearings replacement.
